Summary: Swapped 7700, re-tested tipping bucket

2018-10-25
Sherman Wetland

Joe and I arrived at 9:30 for a maintenance trip. It was sunny and mild, calm with some wispy clouds overhead. Joe scraped off the otter poop from the boardwalk and laid down a wooden lattice structure to hopefully deter future visits.

We swapped the LI-7700 for calibration and to swap out the power board: sn TG1-0423 came down and sn TG1-0424. I connected the 7700 in the 7550 software, reset the box, and then confirmed that GHG data columns were correct and the 7700 was connected. I also updated the heater and cleaning settings to match the original SW settings. This is the first time the LI-7700 data was recorded since 2018-10-04.

LI7700 readings:
(sn TG1-0423 before cleaning --> sn TG1-0423 after cleaning --> sn TG1-0424)
CH4 2.07ppm --> 2.08 --> 2.12
RSSI 61 --> 79 --> 79

LI-7500 readings:
CO2 428ppm
H2O 692ppm
T 17.5C
P 102.1kPa
SS 96

We cleaned and tested the tipping bucket sn 65552-615. Last week, we got 94 tips and adjusted the set screws by one half turn. We connected the bucket to a CR23x and dribbled 475ml of water through it. This should result in 100 tips â€“ we got 96 tips. We adjusted the set screws in the bottom by one full turn clockwise (+4-6%).

We left at 10:05.
